33 .Nd RADIUS client configuration file
38 contains the information necessary to configure the RADIUS client
42 The file contains one or more lines of text, each describing a
43 single RADIUS server which will be used by the library.
45 white space is ignored, as are empty lines and lines containing
48 A RADIUS server is described by three to five fields on a line:
50 .Bl -item -offset indent -compact
63 The fields are separated by white space.
66 character at the beginning of a field begins a comment, which extends
67 to the end of the line.
68 A field may be enclosed in double quotes,
69 in which case it may contain white space and/or begin with the
72 Within a quoted string, the double quote character can
75 and the backslash can be represented by
77 No other escape sequences are supported.
79 The first field gives the service type, either
81 for RADIUS authentication or
83 for RADIUS accounting.
84 If a single server provides both services, two
85 lines are required in the file.
86 Earlier versions of this file did
87 not include a service type.
88 For backward compatibility, if the first
93 the library behaves as if
95 were specified, and interprets the fields in the line as if they
96 were fields two through five.
98 The second field specifies
99 the server host, either as a fully qualified domain name or as a
100 dotted-quad IP address.
101 The host may optionally be followed by a
103 and a numeric port number, without intervening white space.
105 port specification is omitted, it defaults to the
111 file for service types
116 If no such entry is present, the standard ports 1812 and 1813 are
119 The third field contains the shared secret, which should be known
120 only to the client and server hosts.
121 It is an arbitrary string of
122 characters, though it must be enclosed in double quotes if it
123 contains white space.
124 The shared secret may be
125 any length, but the RADIUS protocol uses only the first 128
127 N.B., some popular RADIUS servers have bugs which
128 prevent them from working properly with secrets longer than 16
131 The fourth field contains a decimal integer specifying the timeout in
132 seconds for receiving a valid reply from the server.
134 is omitted, it defaults to 3 seconds.
136 The fifth field contains a decimal integer specifying the maximum
137 number of attempts that will be made to authenticate with the server
139 If omitted, it defaults to 3 attempts.
141 this is the total number of attempts and not the number of retries.
143 Up to 10 RADIUS servers may be specified for each service type.
144 The servers are tried in
145 round-robin fashion, until a valid response is received or the
146 maximum number of tries has been reached for all servers.
148 The standard location for this file is
149 .Pa /etc/radius.conf .
150 But an alternate pathname may be specified in the call to
152 Since the file contains sensitive information in the form of the
153 shared secrets, it should not be readable except by root.
